Tray-based tooth whiteners are custom made trays, similar to a mouth-guard, that are made at your dentist’s office. The trays are filled with a whitening solution, which generally contains a peroxide-bleaching agent. The trays are usually worn for a couple of hours a day to every night for up to four weeks. Treatment length depends on the degree of discoloration of the teeth and the desired level of whitening. The whitening procedure can be done at home and requires no additional appointments or procedures.
There are many ways to whiten your teeth, including toothpastes, over-the-counter gels, rinses, strips, and trays. However, to get the best and fastest results, make an appointment to see your dentist. The whitening products used by dentists and other dental professionals are the safest and most sure way to see immediate results.
